When I am updating my HD 300's flash memory, an error message show up and the updating progress is stopped.
So I disconnected HD 300 from my computer.
Now every time I try to turn on my HD 300 it says "DSP boot failed" on the screen for 2 seconds, and a blank screen followed.
It won't respond to anything now.
It can't be connected to the computer either.
I don't know what to do, please help me!
